Late Tuesday night, San Bernardino County Sheriff's investigators found charred human remains inside the torched property but officials can not confirm they belong to Dorner until forensic testing is completed.

Los Angeles Police Department officials said the condition of the body and the availability of forensic labs will determine how long it will take to identify the remains. It's likely the agencies will expedite analysis, Lt. Andrew Neiman added.

The effort to identify the human remains comes as Riverside police planned today to bury their colleague, Officer Michael Crain, an 11-year veteran on the force and father of two who was allegedly ambushed and killed by Dorner on Thursday. His funeral at 10:30 a.m. at Grove Community Church in Riverside drew thousands of people, including law enforcement from across the state.

Authorities have been hesitant to declare Tuesday's gun fight and fire, which consumed a cabin near Angelus Oaks in which Dorner was suspected to be holed up, the end of the massive manhunt.

But Los Angeles Mayor Antonio Villaraigosa said on CNN this morning the entire region "is breathing a sigh of relief" with the belief that Dorner is dead.

"We do believe is it the body of Christopher Dorner, but we don't know for certain and until we do, the protection for those police officers will continue," Villaraigosa said. "The thing to remember is it is not just their lives, but their spouses, their kids, their families. I have talked with many of them and we are going to protect them until we are reasonably certain it is him."

About a dozen of the 50 or so protective details will continue to guard LAPD officials threatened by Dorner until there is a positive identification that the remains are the suspect's, Neiman said.

The fire erupted Tuesday afternoon after a man deputies suspect was Dorner got into a shooting exchange with Fish and Wildlife officers, as well as sheriff's deputies.

A deputy was pronounced dead at 2:24 p.m. and another had undergone surgery at Loma Linda University Medical Center. He is expected to survive. The deputies' names have not been released and officials did not discuss details about them because they were still notifying family members.

The Riverside District Attorney has already filed murder charges against Dorner for killing a Riverside police officer. He is also suspected of killing an Irvine couple, and wounding an LAPD officer.

Los Angeles Police said the murder investigation against Dorner will continue.

"We don't just stop a murder case simply because we think the suspect in that case is no longer with us," Neiman said.

The department intends to follow up on the more than 1,000 tips received from the public and investigate where there were accomplices or other suspects in the attacks.

The internal review of Dorner's firing and the allegations he made in his manifesto is in its early stages and will also continue, Neiman said. It will be overseen by the inspector general, who reports directly to the Board of Police Commissioners, and by Gerald Chaleff, LAPD's special assistant for constitutional policing.

As for the $1 million reward, Neiman said it's unclear whether anyone will receive it. Rewards are normally given for information leading to arrest and conviction. Assuming Dorner is dead, he said, the city attorney will review the case and decide whether anyone gets a reward.

Villaraigosa said it's possible the reward offered could go to the people who notified police on Tuesday of Dorner's activities.

At the Oaks Restaurant on Highway 38 in Angelus Oaks Wednesday morning, media had already begun gather near a roadblock was being manned by the California Highway Patrol. The site is about six miles from the crime scene.

Ken Verhoef, an Angelus Oaks resident, has been trying to make his way from Carlsbad to his cabin in Angelus Oaks since Monday. He said staying at his home Monday night was nerve-wracking since Dorner was still on the loose.

"I was sleeping on the floor and had my 9mm next to me. It sounded like he was damn close," Verhoef said.

He said he didn't hear gunfire Tuesday, but did hear several helicopters and saw many sheriff's cruisers heading up and down the highway.

The president of the Big Bear Lake Resort Association expressed relief this morning that the manhunt for fugitive Christopher Dorner appeared to be over.

"Our hearts go out to all law enforcement that put their lives on the line to protect Big Bear," said association board president Joyce Reed. "We are especially mournful for the deputy who lost his life during this tragic incident, and we send our deepest, heartfelt sympathy to the deputy's family."

Reed said the Big Bear Lake area is mourning the death of the deputy, but also feeling relief after days of uncertainty regarding Dorner's whereabouts.

Highways 330 and 18 are open, but Highway 38 is only open to residents in Valley of the Falls, Mountain Home Village and Angelus Oaks, Reed said.
